* lcd_st7920: Add brief delay around gpio toggle calls on fast MCUsKevin O'Connor2019-08-101-0/+20
| | | | | | | | | On fast MCUs (like the SAMD51) it is possible for the gpio to toggle faster than the st7920 can accept. Add a small delay around the clock rise signal. Signed-off-by: Lars R. Hansen <popshansen@hotmail.com> Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* spicmds: Rework spi config commandsKevin O'Connor2019-08-067-81/+86
| | | | | | | | | | Rework the spi_config commands so that bus configuration and shutdown message configuration is done separately from the main "config_spi" command. This makes the spi configuration more flexible. It's now possible to use software spi without a CS pin. It's now possible to define multiple SPI messages to send on a shutdown event.

* stm32f1: Remove now unused src/stm32f1/ directoryKevin O'Connor2019-08-0511-1138/+0
| | | | | | | Now that the stm32f1 code has been merged into the stm32 code, there is no longer a need to keep the stm32f1/ directory. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Rename clock.c to stm32f4.cKevin O'Connor2019-08-052-1/+1
| | | | | | | Rename the clock.c file to stm32f4.c to make it more clear that the code is specific to the stm32f4 chips. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Rename stm32f4/ directory to stm32/Kevin O'Connor2019-08-0516-93/+90

* endstop: Rename mcu end_stop commands to endstopKevin O'Connor2019-07-121-35/+35
| | | | | | | | | Rename the commands. The main reason for this change is to force a micro-controller code updated (due to important bugfix in 7fefe52d). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Don't update SF_LAST_DIR if SF_NEED_RESETKevin O'Connor2019-07-121-1/+3
| | | | | | | | If the move is not added to the move queue, then the SF_LAST_DIR setting must not be changed. Otherwise, it could result in an incorrect direction being set on the stepper after a homing operation. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* lpc176x: Reset LPC_UART0->FDR when using serialKevin O'Connor2019-07-101-0/+1
| | | | | | | | | | The popular "LPC17xx-DFU-Bootloader" alters the LPC_UART0->FDR register, so be sure to reset it back to its default when using serial in Klipper. Reported by @b-vs. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

| | | | | | | | Commit 1096075d changed CONFIG_CLOCK_FREQ to the actual cpu frequency, but that commit failed to update adc.c accordingly. That made the adc run 4 times slower. Make the corresponding change to adc.c. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
